Peter, I do relatively little processing on my images. I stack in AS3! using typically 1500 out of 2000 frames (8-bit, not 12 or 16). I process the resulting PNG files in Registax using wavelets 2, 3 & 4 and a slight gamma adjustment to brighten the darker areas: this is to enhance the prominences. I don’t do a histogram stretch because the gain and exposure time are set so that the maximum brightness in the sharpened images is at about 80%. On most days I will capture around 10 videos if the clouds permit, and I compare the resulting images to find the sharpest of them to post here.
